attached in Andrew/RFS direct mount antenna. If the
small O-n‘ng is used for TRP direct mount installaa'an, a
gap may occur between TRP and antenna for RF
interface Therefore it can not be used as watertight

If orderwire communication is required, connect the X08] 8A OW/RX
LEV Monitor unit to the TRP. The OW/RX LEV Monitor unit operates on
a dry battery (6F22/9V),
Notes: 1. Insert the battery with eorrect polarity.
2. When the OW/RX LE V Monitor will not being axed for long
periods of time, remove the battery to avoid damage from
battery leakage and corrosion
3. Set the OW switch to ON when the orderwire is used. If" the

PRECAUTIONS
2. PRECAUTIONS
The following precautions must be carefully observed during
maintenance.
(a) The maintenance personnel should report arrival at and departure
from a station to the relevant station. The following are dangers
and warnings to the maintenance personnel.
Warning: 1. The —43 V DC power is superimposed on the center
conductor of the 1/17 cable between the MDP and the
TRP. Connecting test equipment directly to this terminal
may damage it and touching the coaxial cable core may
cause electrical shock.
2. Persons performing servicing must take necessary steps
to avoid electro-static discharge which may damage the
modules on the MDP or cause error. Wear a conductive
wrist strap connected to the grounded (6) jack on the front
of the equipment shelfi This will minimize static build-
up during servicing (see Fig. 2-1).
3. Do not disconnect the I/F cable between the MDP and
the TRP in operating condition, to avoid damaging the
MDP and TRP. Do not remove/connect the I/F cable with
the MDP power ON, turn the MDP power OFF before
connecting/disconnecting the I/F cable.
4. After turning ON the equipment, wait at least 1 minute
before turning it OFF again. Repeatedly turning the
power ON and OFF within a short interval may cause the
MDP to fail.
5. Contact NEC before program download an the LCT is
performed. Equipment may not fimction correctly with
improper op eration.
Caution: I. Be careful that top surface of the MDP is considerably
hot.
(b) During maintenance, the MDP should be set to maintenance
condition by the local crafi terminal (LCT) (see Chan 3-1).
(c) To avoid service interruption under the maintenance, perform
manual protection switching in 1+1 system.
Note: When protection switching has been automatically
completed during a fault, keep this condition by manual
protection switching operation.
(d) First set the MAINT mode to “ON” before selecting the other
items on the LCT maintenance menu.

PRECAUTIONS
Information on the maintenance and the control such as TX SW,
RX SW, Mute, CW, LB, etc. is released if the power is turned ofi‘
or the RESET switch is pressed.
While the CPU is initialized by pressing the RESET switch,
alarm(s) is in normal condition. Afier initialization, the alarm
information is properly provided through relay contacts.
Service will be interrupted instantly by pressing the RESET
switch.
When the control such as TX MUTE, CW, LB, etc. is performed,
set TX SW and RX SW to the same channel certainly. If it carries
out in AUTO condition, it may not operate normally.
instantaneous interruption may occur when performing the TX SW
manual switching operation.
Before removing or installing the MDP/TRP. turn off the power
switch on the MDP.
For procedures to change the password, refer to the Appendix in
this section.
After equipment start-up, allow the equipment to warm up at least
30 minutes.
(m) After completing maintenance, restore all connections and manual
switch(es) to normal and confirm that all red alarm LEDs are unlit.
Note: ‘ The MD Unit No.2 is notpmvidsdfar 1 +0 system.
